· Summary. This paper addresses a problem pertinent to the design of landing strings and drillstrings for deepwater operations. These landing strings are designed to run long and heavy casings, tiebacks, or liners (typically deep intermediate and production tubulars), and the total weight may approach or exceed 1,000 kilo lbf (klbf) at the mudline.

· This energy is transmitted from the rock drill via the shank adapter, drill rod, and drill bit to the rock, where it is used for crushing. The top hammer method is primarily used for drilling in hard rock for hole diameters up to 5 in (127 mm), and the main advantage is the high penetration rate in good solid rock conditions.

Abstract. The fundamental principles of rock fragmentation by crushing, blasting, and drilling are not well understood; however, empirical observations have provided means for predicting the energy requirements for these processes. Experimental procedures and methods of analysis used in comminution studies are described in this review.
